MAIF Case Study on Mainframe Modernization

This case study details the modernization efforts of MAIF, a French mutual insurer with 4.2 million members, as they transitioned from aging mainframe systems to a more flexible Unix-based architecture using Rocket Visual COBOL. The document outlines the challenges faced by MAIF, including the need to enhance operations, meet evolving customer expectations for digital self-service, and mitigate business risks associated with aging infrastructure. The solution involved a service-oriented architecture (SOA) and Java integration, which improved flexibility and user experience. Key results included a significant increase in batch processing speed, achieving up to 20% faster processing without compromising data integrity. The seamless migration process ensured uninterrupted access to online services for members, thereby maintaining business continuity. This case study serves as a practical example of how organizations can modernize critical systems while minimizing disruption to existing business logic and operations.
